Statement of problem: Amelogenesis imperfecta (AI) is a genetic disorder that causes defective enamel development in both primary and permanent dentition. Significant tooth structure damage often results in occlusal disharmony affecting the patient’s occlusal vertical dimension (OVD).
Purpose: The purpose of this study was to review the current data in OVD evaluation and its reestablishment during the treatment of amelogenesis imperfecta patients.
Method and Materials: Relevant publications on OVD evaluation in amelogenesis imperfecta patients were thoroughly reviewed from the literature published between the years 1994 and 2014: With no restrictions criteria on the language of publications or the types of articles. The search strategy was developed using a combination of controlled vocabulary and the final update was stopped on November 2014.
Results: The exploration of Medline identified, in this systematic review, 20 articles. Only 13 of them were selected after screening. All the studies were case reports describing 14 patients (7 males/ 7females, age: from 7 to 45 years old) with amelogenesis imperfecta treated with different approaches. While OVD was modified in 13cases, there was a lack of information concerning the OVD evaluation and treatment.
Conclusion: According to this study, it seems important to systematically explore OVD in all AI patients, to preferably evaluate it by cephalometric method and to reestablish it by a prosthetic approach
